Sec. 11E-115. Limitations on contesting boundary change. Neither the People of the State of Illinois, any person or corporation, private or public, nor any association of persons shall commence an action contesting either directly or indirectly the dissolution, division, annexation, or creation of any new school district under the provisions of this Article, unless the action is commenced within one year after the date of the election provided for in this Article if no proceedings to contest the election are duly instituted within the time permitted by law, or within one year after the final disposition of any proceedings that may be so instituted to contest the election; however, where a limitation of a shorter period is prescribed by statute, the shorter limitation shall apply, and the limitation set forth in this Section shall not apply to any order where the judge, body, or officer entering the order being challenged did not at the time of the entry of the order have jurisdiction of the subject matter.
